Gibbo Posted February 13, 2011 Share #1 Posted February 13, 2011 Advertisement (gone after registration) ... use by date by more than ten years only fit for the bin? Or is it worth giving it a go? Link to post Share on other sites More sharing options...

andybarton Posted February 13, 2011 Share #2 Posted February 13, 2011 Colour or black & white? How has it been stored? Link to post Share on other sites More sharing options...
Gibbo Posted February 13, 2011 Author Share #3 Posted February 13, 2011 It's black & white (Ilford HP4) and has been stored in a box of 4 on the top shelf of a wardrobe. Dry & coolish. Link to post Share on other sites More sharing options...
cbretteville Posted February 13, 2011 Share #4 Posted February 13, 2011 I just souped a roll from a 150 foot bulk roll of Kodak TechPan that was bought about 1987 and not stored very well. Looks fine. Carl Link to post Share on other sites More sharing options...
Gibbo Posted February 13, 2011 Author Share #5 Posted February 13, 2011 Sounds promising. I'll give it a go. Link to post Share on other sites More sharing options...
earleygallery Posted February 13, 2011 Share #6 Posted February 13, 2011 Just try it, you have nothing to lose! It will certainly give you results. Link to post Share on other sites More sharing options...
adan Posted February 14, 2011 Share #7 Posted February 14, 2011 Advertisement (gone after registration) I'd "rob" one of the rolls (i.e., shoot about 6-10 test frames, rewind, cut off the first 30% of the roll (in the darkroom, obviously ) to process, and save the remaining film in the cassette as a "20-exposure roll." Most likely defect of aging would be base fog - overall darkening or graying of the unexposed areas due to cosmic rays or other penetrating radiation over time. BTW if this is actually HP4 (and not HP5 or FP4) - it must be WELL past the expiration limit, since HP4 was discontinued in 1976. However it is probably still usable.

Xmas Posted February 14, 2011 Share #8 Posted February 14, 2011 Hi If you have a lot of film you can use an anti fog agent in the dev - google. If it is going to be foggy it will slow the effective speed try 2/3 of a stop slower. Even if it is foggy it wont necessarily show on a scan or print, apart from reducing shadow (effective) density, hence the 2/3 of a stop.

Gibbo Posted February 14, 2011 Author Share #9 Posted February 14, 2011 Would it be a very different answer if it was colour film? Link to post Share on other sites More sharing options...
Xmas Posted February 14, 2011 Share #10 Posted February 14, 2011 Yes, there is relative shift of speed in the three layers to worry about. I'd not shoot a wedding on old film some brides can kick real hard. Noel Link to post Share on other sites More sharing options...
Gibbo Posted February 14, 2011 Author Share #11 Posted February 14, 2011 I shall bear that in mind Link to post Share on other sites More sharing options...
tobey bilek Posted February 14, 2011 Share #12 Posted February 14, 2011 bracket the exposures on the 12 frame test to determine effective speed. It has probably lost speed and contrast and picked up some base fog. Compensate as instructed above. You will never get it to work as new in any case. If the film was frozen, you would have a much better chance. Link to post Share on other sites More sharing options...
wattsy Posted February 14, 2011 Share #13 Posted February 14, 2011 If the film was frozen, you would have a much better chance. Only up to a point. A freezer will not provide any protection against cosmic and other background radiation. Link to post Share on other sites More sharing options...
wildlightphoto Posted February 14, 2011 Share #14 Posted February 14, 2011 Would it be a very different answer if it was colour film? I don't know about color film in general, but for Kodachromes (no longer a question) color shifts, loss of contrast and base fog would be expected even for frozen film, and slower speed film would have a much better chance of recording a usable image than fast film. I wouldn't try color film ten years past expiration that had been stored at room temperature. Link to post Share on other sites More sharing options...
